The Low Impact Development Design Group, or LIDDG, manufactures and distributes two storm water best management practice (BMP) product lines.

LIDMIX is a media that is designed to treat the heavy metals zinc (Zn), copper (Cu), and lead (Pb), as well as other metals and non-point source runoff stormwater pollutants. The media can be used in existing media-based stormwater treatment devices, such as cartridges and filters, to enhance their performance.

The other product is LIDMAT™, for which LIDMIX™ media is inserted into a geotextile mat that is formed into modules that can be attached to each other to treat sheet flow or attached to a storm drain structure. A biodegradable version of the LIDMAT™ is also available. It can be planted with hyper accumulators, which will enhance the capture of pollutants.
